The public is encouraged to "throw crumbs onto the carpet, watching as Ivanka elegantly vacuums up the mess, her smile never wavering".

A large text description of the work hanging on the gallery wall describes Ms Trump as "a figure whose public persona incorporates an almost comically wide range of feminine identities - daughter, wife, mother, sister, model, working woman, blonde".

It also describes her as a "contemporary feminine icon" and an avatar for the complexities of modern femininity.

The text adds that the act of throwing breadcrumbs onto the carpet for her to vacuum is "surprisingly pleasurable".

Ms Trump, a senior White House adviser, tweeted along with a link to the story: "Women can choose to knock each other down or build each other up. I choose the latter."

Donald Trump Jr tweeted: "Sad, but not surprising to watch self-professed 'feminists' launching sexist attacks against @IvankaTrump. In their crazed world, sexism is OK if (it) hurts their political enemies."

Eric Trump called his sister a "powerful woman who has done more for women than probably anybody in Washington DC" on Fox News.

Sad, but not surprising to watch self professed “feminists” launching sexist attacks against @IvankaTrump. In their crazed world, sexism is OK if hurts their political enemies.

That's ok, they can go put on their stupid hats & she’ll get back to actually fighting for women. https://t.co/yxXIDz2R8e
